Abstract (en)

A method, medium, and system efficiently rendering 3 dimensional (3D) graphics data. The rendering method includes calculating the strength of a fog effect that is to be applied to graphics data, determining whether texture mapping must be performed on the graphics data, according to the strength of the fog effect, and performing the texture mapping according to the determination result. Accordingly, it is possible to reduce the number of memory access operations for reading textures.
